| Research Abstract |
We consider the following modified Prisoner's Dilemma : Nature chooses the order of moves with 50-50 chance and only the first mover's Defection is observed by the second. When the payoff structure satisfies a certain condition, there exists a Nash equilibrium in which both players choose Cooperation in its play. The purpose of this study is to test the hypothesis that the possibility of cooperation is enhanced in the modified Prisoner's Dilemma in comparison with the usual one. By an experiment, this hypothesis was supported at the 1% significance level when the incentive for Defection is in a certain range.
